PRIORITY

The present invention claims priority under 35 USC section 119 based on a provisional application 60/852,909 filed Oct. 18, 2006.

FIELD OF THE INVENTION

The instant invention relates generally to mechanisms of loose leaf binders and particularly to a binder assembly device for quickly and easily binding sheets such as papers to create an instant booklet or presentation file.

BACKGROUND OF THE INVENTION

Ring binders are well-known tools for storing, displaying and organizing paper and other similar materials and are useful in a variety of settings; for example, in schools and offices. Ring binders are produced in many different shapes, styles and sizes for both aesthetic and functional purposes. The size is usually dependent upon the diameter of the ring closures, non-limiting examples include, ring closures of a half-inch, one inch, one and a half inches, 2 inches, 3 inches, 4 inches and 5 inches in diameter. Additionally, the rings can be crafted into various shapes for different purposes, non-limiting examples include, D-ring and continuous curvature.

While binders can be crafted in a variety of shapes, styles and sizes; they all generally share the same common binder ring mechanism. This mechanism is usually spring-loaded and when engaged will quickly and efficiently clamp together to join opposing sides of the rings of the binder. However, due to the pressure exerted on the spring mechanism from repeated use, part and/or all of the ring and/or rings move out of alignment and cease to clamp tightly together. The ease of sifting through the contents of the ring binder is impaired and items may be lost from the binder due to slipping out from misaligned rings. This misalignment of the rings essentially destroys the function of the binder.

DESCRIPTION OF THE PRIOR ART

U.S. Pat. No. 4,690,580 discloses a ring binder mechanism of the type referred to wherein the ring portions are reliably adjusted on all sides in their closed position even with heavy loading and are secured against opening of the ring closure by displacement of the ends of the ring portions.

U.S. Pat. No. 5,765,956 discloses a device for perfected closure of the mechanism having flat rings for containers of mobile sheets (binders). The device comprises rings and screws which are formed with a single presswork operation together with a strip to be placed at the disposal of the user. The latter with simple coin screws within suitable orifices formed on the strip, the latter being fixed to the internal surface of the folder. There is also provided that each ring may be closed simply by causing projections which are formed on the base of each ring to penetrate within shaped grooves, the latter being formed at the opposite end of the same ring, an operation which is easy due to the elasticity of the material which constitutes the rings.

U.S. Pat. No. 7,125,190 discloses a ring binder assembly device that can both prevent misalignment of binder rings and repair binder rings which have become misaligned. The device of the preferred invention is both a resilient and flexible structure which substantially surrounds the existing binder rings. The device is comprised of at least two hollow tubes of continuous curvature which engage upon closing of the rings to form a single unit. The hollow tubes are sized to substantially cover the entire underlying binder ring and each can be formed as unitary or segmented elements. Since it has been theorized that a funnel-shape can guide a smaller object to a specific point, one end of one of the hollow tubes is molded into a funnel-shape. Through use of this funnel-shape, the device of the instant invention renders it possible to guide one part of a ring to the other part of the ring, thus preventing misalignment and forcing the rings to realign properly should they be out of place.

Standard folders, binders, report covers and other types of paper filling products can be cumbersome, bulky, flimsy or difficult to use. Many devices are simply suited to holding a single type of paper and do not provide effective binding to pages with other dimensions.

DETAILED DESCRIPTION

FIG. 1 illustrates the clip binder 100 of the present invention. The clip binder 100 includes a flexible housing 104 which is shown as a substantially D shape and may be formed from an elongate flexible sheet of plastic or other suitable material. A clip binder 100 includes an upwardly extending rod 102 to cooperate with holes formed in sheets (not shown) to hold the sheets in position. Furthermore, the upwardly extending rod 102 cooperates with the flexible housing 104 to prevent the sheets of the user from coming off the upwardly extending rod 102. The upwardly extending rod 102 may be rigid and could be formed from metal, plastic or any suitable material.

The upwardly extending rod 102 could have a rectangular, triangular or any other suitable cross section and may have an inwardly sloping end to facilitate the cooperation with the flexible housing 104 and the sheets of the user. The flexible housing 102 includes an aperture 112 to accept the upwardly extending rod 102.

FIG. 2 illustrates a cross-section of the flexible housing 104 and the upwardly extending rod 106. As shown in FIG. 2, the flexible housing 104 includes a top section 130, an opposed bottom section 132, and a side section 134. The side section 134 includes a first curve section 120 which is connected to a first sloping section 126 which is connected to a second curve section 122. The second curve section 122 is connected to a second sloping section 128 which is connected to a third curve section 124 which is connected to the bottom section 132. The first curve section 120 is connected to the top section 130. The opposing side of the flexible housing 104 is open to accept sheets of the user. The bottom section 132 has the upwardly extending rod 106 mounted near the open side of the flexible housing 104, and the upwardly extending rod 106 is substantially perpendicular to the interior surface of the bottom section 132. The first curve section 120, the second curve section 122 and the third curve section 124 contribute to the flexibility of the flexible housing 104. The aperture 112 may be reinforced with a metal lining along the interior surface in order to maintain the diameter of the aperture 112. The upwardly extending rod 106 includes an upper narrowed section 108 and a lower narrowed section 110 to cooperate with the aperture 112, and each of the upper narrowed section 108 and the lower narrowed section 110 is of reduced diameter which corresponds approximately to the diameter of the aperture 112. Consequently, the top section 130 will remain detachable fixed to the upwardly extending rod 106. The top section 130 may be positioned at the upper narrowed section 108 in a first position to give the clip binder 100 a larger capacity to hold the sheets of the user. The top section 130 can be removed from the upwardly extending rod 106 so that the sheets of the user can be removed, or the top section 130 can be moved along the upwardly extending rod 106 until the aperture 112 is positioned at the second narrowed section 110 at a second position. At the second position, the clip binder 100 may have less capacity for sheets of the user.

FIG. 3 illustrates the top section 130 positioned at the second narrowed section 110. By positioning the top section 130 at the second narrowed section 110, the clip binder 100 may be able to hold a reduced number of sheets, but the top section 130 can be more securely held onto the upwardly extending rod 106 because if the top section numeral 130 should slip off the upwardly extending rod 130 at the second narrowed section 110, the top section 130 should be held at the first narrowed section 108. Consequently, the top section 130 is a less likely to become unintentionally detached from the upwardly extending rod 106.

FIG. 4 illustrates a side view of the clip binder with the shorter upwardly extending rod 106.

FIG. 5 illustrates a top view of the clip binder 500 showing two upwardly extending rods 106 positioned in two apertures 112 to bind the sheets of the user along the top of the sheets.

FIG. 6 illustrates a top view of the clip binder 600 showing three of upwardly extending rods 106 positioned in the three apertures 112 to bind the sheets of the user along the side of the sheets. The clip binder 600 may be appropriate for letter size sheets.

FIG. 7 illustrates a top view of the clip binder 700 showing four upwardly extending rods 106 positioned in four apertures 112 to bind the sheets of the user along the side of the sheets. The additional aperture and upwardly extending rod may be appropriate for legal size sheets.

FIG. 8 illustrates a side view of the clip binder 800 with an integral back cover 140. The bottom section 132 is shown as being formed integral with the back cover 104. The back cover 104 serves to protect the sheets of the user and provide a smooth writing surface for the sheets of the user.

FIG. 9 illustrates a side view of the clip binder 900 with the integral back cover 140. FIG. 9 shows a longer upwardly extending rod 106 so that additional sheets of the user can be held.

FIG. 10 illustrates a side view of the clip binder 1000 with the top section 130 that has been detached from the upwardly extending rod 106.

FIG. 11 illustrates a perspective view of the clip binder 1100. The clip binder 1100 includes a top section 130, upwardly extending rod 106 and a back cover 140.

FIG. 12 illustrates a top view of the clip binder 1200. The top section 1230 of the clip binder 1200 includes a reduced width edge in the transverse direction that does not extend to the edge of the bottom section 1232. The clip binder 1200 could be extended for legal size sheets or could be used for letter size sheets.

FIG. 13 illustrates a top view of the clip binder 1300 which extends along the side of the letter size sheets and illustrates three apertures 112.

FIG. 14 illustrates a top view of the clip binder 1400 which extends along the side of legal size sheets and illustrates four apertures 112.

FIGS. 15-18 illustrates removable covers 150 which can cooperate with the clip binders shown in FIGS. 1-14. The removable cover 150 includes a cover aperture 152 which cooperates with the upwardly extending rod 106, and the removable cover 150 is placed under the top section 130 to be secured. FIG. 15 illustrates three cover apertures 152 along the side to cooperate with the clip binder 1300 as shown in FIG. 13.

FIG. 16 illustrates a removable cover 150 having two cover apertures 152 along the top of the removable cover 150 to be used in cooperation with the clip binder 1200 illustrated in FIG. 12.
